Provide an explanation
Please provide a terse explanation for what 'push broom' means. Raster scan? Boustrophedonic scan? Is the sensor scanning back and forth, or staring in a thin line as the spacecraft progresses forward? 12.33.223.211 (talk) 02:41, 24 January 2018 (UTC)
 * Neither - those first two would both be a whisk broom scanner. The push broom is a fixed line, moving perpendicular to its axis. Domestic document scanners are a familiar example.
 * The advantage is few parts as there's no need for a scan axis, the downside is that the sensor needs to have many pixels. Andy Dingley (talk) 10:40, 24 January 2018 (UTC)
